Abstract

Abstract A target region of tissue is destroyed by saturating the region with light-absorbing material, reducing the temperature of the region, and disintegrating the region with a light source. One means for carrying out these steps is a multi-channel delivery needle having a primary transport line, a waveguide lengthwise connected to the primary transport line, and one or more auxiliary lines lengthwise connected to the primary transport line. The tubes and waveguide define a sharpened common end to assist the needle in entering the skin and penetrating flesh necessary to reach the target region.
